Mainline Sectional Repair

Key Features:

LMK’s Performance Liner® Sectional process renews pipes from 6 to 36 inches in diameter and in continuous lengths up to 50 feet. The liner can be inverted anywhere in the pipe with no trimming or cutting. The result is a structural, root proof, water-tight seal. Performance Liner Sectional conforms 100% to ASTM F2599. Gasket sealing technology is used at the terminating points of the liner by embedding LMK patented Insignia™ Hydrophilic O-Rings between the liner and host pipe to ensure a water-tight seal.
Compressible material is incorporated at the upstream and downstream ends of the liner for a smooth tapered transition to the old host pipe. During the positioning process there is no resin loss, because the liner is fully contained in the launch hose. Resin comes in contact with the pipe only at the point of repair and migrates into fractures and open joints creating a mechanical lock. Unlike other less precise systems, air pressure is never dropped, which would allow jarred sections of pipe to collapse onto the liner causing further damage and a potential dig. Other 2-step inversion systems also have an uneven resin distribution from the crown to the invert of the pipe. Performance Liner Sectional Repairs are a one-step, long-term, CIPP solution.

    ASTM F2599

    Standard Practice for The Sectional Repair of Damaged Pipe By Means of An Inverted Cured-In-Place Liner

    Significance and Use

    Purchase the full version of this standard by visiting the ASTM website here. This practice is for use by designers and specifiers, regulatory agencies, owners, and inspection organizations who are involved in the rehabilitation of sewer service laterals and its connection to the main through the use of a resin-impregnated tube installed within an existing sewer lateral. As for any practice, modifications may be required for specific job conditions.

    1. Scope

    1. This practice covers requirements and test methods for the sectional cured in place lining (SCIPL) repair of a pipe line (4 in, through 60 in. ) by the installation of a continuous resin-impregnated-textile tube into an existing pipe by means of air or water inversion and inflation. The tube is pressed against the host pipe by air or water pressure and held in place until the thermo set resins have cured. When cured, the sectional liner shall extend over a predetermined length of the host pipe as a continuous, one piece, tight fitting, corrosion resistant and verifiable non-leaking cured in place pipe.
    2. The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that provided for information only and are not considered standard.
    3. There is no similar or equivalent ISO Standard. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Particular attention is drawn to those safety regulations and requirements involving entering into and working in confined spaces.
